6.1.2 Handling of the spring terminals
All terminal connections of the controller are implemented with mating connectors with spring terminals (push-in
spring connection) and have the following characteristics:
Conductors with cross sections between 0.25 and 2.5 mm² can be used.
All mating connectors are coded and any reverse polarity is therefore ruled out.
A - Installation
For fast installation without tools, direct conductor connection of prefabricated cables (these with 10 mm wire
end sleeves) by simply inserting into the spring terminal is also possible. The orange push button must also be
pressed during insertion to connect flexible wires of 0.25 to 2.5 mm² without wire end sleeve.
B - Disconnetion
The wires are disconnected using a screwdriver (max. 3.5 mm width) via the orange push button at the terminal
connection that has no direct contact to live parts.
Step 1: Press the orange push button vertically downwards using a screwdriver to detach the connection.
Step 2: Pull wire upwards.
C - Test
For voltage testing, each terminal connection has openings for probe tips of multimeters that are designed with
protection against direct contact.
NOTICE
Risk of damage! All mating connectors must always be guided vertically and attached / disconnected
without twisting so that the pins on the main board are not bent and damaged.
